Re: Security issue in Microsoft Outlook

How is this any different than having the text of a link say something other
than the URL?  This is possible in HTML (in any application) and Microsoft
Office application.  For example, go into Word and type "some text" then
highlight it, and press Ctrl+K.  Then type in the URL you want.  This is now a
hyperlink.  Also note that the tool tip should show the correct link.

This is essentially the same as the following HTML:
<A HREF="http://evil";>http://safe</A>

Quoting Bakchodiya <bakchodiya () yahoo com>:

An issue has been discovered in MS Outlook (All
Versions) where anyone can fake a URL & send it
across.

How does it work:

Lets compose an email in MS Outlook, lets type


http://www.cybertrion.com & put a space after it to
make it a link. Now put your cursor just before
cybertrion & type any URL for eg:
http://www.foo-labs.info now send it to anyone. The
receiver will see the URL as http://www.foo-labs.info
but when he clicks on it it will directly take him to
http://www.cybertrion.com

I am not sure how critical this is but it can fool
alot of people & result in download of a virus.
